Plain soap is not bacteriostatic or bactericidal; instead, it works by physically removing microorganisms from the skin surface. The mechanical action of rubbing the hands together and rinsing off the soap helps to dislodge and wash away bacteria, viruses, and other germs that may be present on the skin. This reduces the overall number of microorganisms on the hands and helps to prevent their spread to other people or surfaces.
